The user interface (UI), in the industrial design field of human–computer interaction, is the space where interactions between humans and machines occur.

The goal of this interaction is to allow effective operation and control of the machine from the human end, whilst the machine simultaneously feeds back information that aids the operators' decision-making process.

Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls, and process controls.

The design considerations applicable when creating user interfaces are related to or involve such disciplines as ergonomics and psychology.

Information is that which informs.

In other words, it is the answer to a question of some kind.

It is thus related to data and knowledge, as data represents values attributed to parameters, and knowledge signifies understanding of real things or abstract concepts.

As it regards data, the information's existence is not necessarily coupled to an observer (it exists beyond an event horizon, for example), while in the case of knowledge, the information requires a cognitive observer.
